2 Claims.

My invention relates to new and useful improvements in filters and moreparticularly to a removable distribution nozzle and means for holdingthe same that may be readily installed in water filters, softeners orthe like.

As is well known to those skilled in the art. in both the high pressurefilters or the gravity type of filters the usual arrangement is toprovide a tank in which gravel, sand or Zeolite is placed in the tankwhile in the bottom thereof there are placed nozzles, but when it isdesired to clean the nozzles, it is necessary to remove the sand and thedifferent layers of gravel, etc.

In other instances, tanks have been made with false bottoms but thedistribution nozzles have been hard to remove or to renew.

Another object, therefore, of the present invention is to provide afalse bottom for the filter tank in which there are to be located a.plurality of internally threaded sockets, each socket in turn to receivea distribution nozzle that is relatively small in cross-section andprovided with a pointed nose. The nozzle follows the shape of aprojectile so that when it is desired to clean a nozzle or nozzles, itis a relatively simple matter to enter the tank through a manhole underthe false bottom and withdraw, that is, draw downwardly the projectileshaped nozzle, thoroughly cleanse the same and then insert it again inthe false bottom and force the nose of the nozzle upwardly through thelayer of rocks or gravel where it will be finally tightened in place.

Still another object of the invention is to provide a distributionnozzle which is cylindrical in shape having a pointed nose together witha plurality of longitudinally extending slots or orifices through whichthe water or liquid may pass into the nozzle and then downwardly intothe distribution chamber. The nozzle is threaded externally about midwayof its length to engage the internally threaded socket, while the lowerend of the nozzle is provided with a flange so that it can'be pulled uptightly against the undersurface of the false bottom. The rear end ofthe nozzle is slotted so that it is a simple matter .to put a wrench orbar within the slot to pull the nozzle tightly up in place.

Still another object of the invention is to provide a false bottom withthe plurality of sockets secured therein, this false bottom being shapedto fit within the wooden tank, metal tank or concrete tank depending onthe form of tank installation.

Still another object of the invention is to provide a special form ofsocket and distribution 2 nozzle so that with tanks already installed itwill be a relatively simple matter to build a false bottom, install thesockets therein and then install the false bottom and the quicklyremovable and replaceable distribution nozzles.

With these and other objects in view, the invention consists in certainnew and novel ar rangements and combination of parts as will behereinafter more fully described and pointed out in the claims.

Referring now to the drawing showing 'one form of installation:

Fig. 1 is a fragmentary sectional view of a water filter or. softenerhaving a false bottom therein in which are fitted the distributionnozzles; Fig. 2 is a fragmentary top plan of the false bottom showingthe sockets arranged therein;

Fig. 3 is an enlarged fragmentary sectional view showing a portion ofthe false bottom, socket and distribution nozzle in position; and

Fig. 4 is a sectional view taken on line 44 of Figure 3.

Referring now more particularly to the several views and to Fig. 1 forthe moment, there is fragmentarily shown a filter tank I having thebottom 2, the manhole 3, and the outlet 4. There is also shown the falsebottom';5 which is supported by the inner ring 5, while' above this maybe seen the ring 1, and the uprights and supports 8.

It will be understood that if the tank is made of concrete or wood ormetal, this false bottom will be installed in the best-manner to supportit.

- Also, if the wooden or concrete tank is not pro vided with a manhole,this will be done so that an operator can climb under the false bottom,or in other words, in the resultant distribution chamher, and insert orreadily remove the distribution nozzles about to be mentioned. 1

In Fig. 1, I have also shown layers of gravel 9 and above these layersof gravel may be the sand or Zeolite I0 or any desired filtering mediumforming the filter bed.

It will be understood that in Fig. 1, I have only shown the filteringmaterial or bed in one corner but this is only for simplicity ofillustration.

Referring for the moment to Fig. 2, I have fragmentarily shown the falsebottom 5 together with the rows of sockets H. Each socket, as may beseen in Figures 3 and 4, consists of the circular top plate I2 with adepending hub l3 which is internally threaded as at H, while preferablyfour screws l5 are passed through spaced holes in the plate I! totightly hold this socket in place.

which is provided with a plurality of vertical. I

extending slots or orifices l9 that extend down to the level of the topplate of the socket l5 when the nozzle is in place. These orifices aredistrib uted around the circumference of the nozzles so that the liquidmay filter through these relatively narrow openings.

About centrally of the length of the nozzle is what I term a lower bodyportion 20, slightly larger in diameter and externally provided with ascrew thread 2| to engage the internal threads of the socket. Near therear end of the lower body portion 20 is the flange 22 so that thedistribution nozzle may be pulled up tightly to seat against the bottomof the false bottom as well as be secured in the socket.

Below the flange 22 the body extends down slightly as at '23 and thisportion is provided with a kerf or slot 24 so that a bar or wrench maybe put within the kerf and the distribution noz- 'zle quickly threadedup into its socket, or in a like manner may be quickly removed. Thus,the filtered liquid, after passing through the sand and the gravel orother filtering material, may pass in these distribution nozzles and outthe bottoms thereof into the distribution chamber 25, or in other words,the space between the true bottom and the false bottom.

As is well known, to ordinarily clean the filter after it has been run acertain length of time, the pressure is reversed so that the nozzles winbe cleansed as well as the filtering material, but'it is also well knownafter this has been done for a certain length of time, it is necessaryto remove the nozzles as they are in time bound to clog or fill withlime, salts, or other foreign material.

With my installation just above outlined, should it be found that thefiltering is not progressing as rapidly as it is supposed to, it is asimple-matter for an artisan or workman after the distribution chamberhas been emptied, to climb in through the manhole 3 and take out any orall of the sockets by simply placing a bar or wrench in the kerf 24 andturning the nozzle in an anti-clockwise direction. The orifices I9 thenmay be quickly cleaned and it is a simple matter to again install thenozzles as their dome or pointed shape noses will easily forcethemselves up, when turned, into the adjacent layers of gravel.

Thus, it will be seen an installation of this kind saves several hoursof time over the ordinary 4 form of filter or water softenerinstallation, as the workman does not have to get in the tank and shovelout all the filtering material to get at the distribution nozzle.

Also, with the other form of filter nozzles that I am familiar with, thefilter nozzles are rather large in cross-section and difiiculty would beencountered in trying to force a nozzle up into the gravel or filteringmaterial.

From the foregoing it will be seen that I have provided new and noveldistribution nozzles together with receptive sockets, these sockets inturn to be installed in a support or false bottom that in turn may bereadily built into new tanks or be accommodated in tanks already made,whether of the high pressure type or the gravity type or'whether theyare made of wood, concrete or metal.

The sockets and nozzles may be made of a standard sizeso that if onecorrodes or wears, or becomes damaged, it is a simple matter to installOne from extra stock. It will also be understood that these nozzles maybe of any desired metal or may be made of an alloy, if the tank is tocontain a liquid that might otherwise affect the nozzle.

Many slight changes may be made without in any way departing from thespirit or scope of the invention.

Having thus described what I claim is new and desire to secure byLetters Patent is:

1. In a filtering tank, a false bottom, a plurality of internallythreaded cylindrical sockets fitted therein and a plurality ofcylindrical shaped distribution nozzles threaded in saids'ockets', eachof said nozzles provided with a pointed nose, the upper portion of thenozzle also having openings adapted to permit the liquid to pass intoand out of the nozzle, the lower portion of the nozzle provided aboutcentrally of its length with external threads and a flange near itsbottom to thus bind the nozzle from the opposite side of the falsebottom and the said nozzles adapted to be inserted and removed from theundersurface of said false bottom.

2. In a filtering tank having a false bottom an internally threadedcylindrical socket fitted in the top surface of the said bottom, acylindrical projectile-like shaped nozzle closed at it upper end, thenozzle provided with a plurality of slots extending around itscircumference, the lower portion of the nozzle being slightly larger indiameter than the upper portion and provided with external threadsadapted to fit within the threads of the socket, a flange near the lowerend of the nozzle and adapted to seat against the undersurface of thefalse bottom to thus bind the nozzle from the opposite side of the falsebottom the lower end of the nozzle also provided with receptive meansadapted to receive a tool for threading the said nozzle into and out ofits receptive socket, from the undersurface of said false bottom.
